Looks good to me. On the C3 box which kicked all this off:

# ldd `which ssh`
        libutil.so.1 => /lib/libutil.so.1 (0x40016000)
        libz.so.1 => /lib/libz.so.1 (0x4001a000)
        libnsl.so.1 => /lib/libnsl.so.1 (0x40028000)
        libcrypto.so.0.9.7 => /usr/lib/libcrypto.so.0.9.7 (0x4003b000)
        libc.so.6 => /lib/libc.so.6 (0x4012d000)
        libdl.so.2 => /lib/libdl.so.2 (0x4023d000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)

# LD_DEBUG=libs ldd `which ssh` 2>&1 >/dev/null | grep -A 11 'find 
library=libcrypto'
00915:  find library=libcrypto.so.0.9.7; searching
00915:   search cache=/etc/ld.so.cache
00915:  lib->hwcap(u)=80000
00915:  lib->hwcap(l)=8000
00915:  *hwcap=803135
00915:  *hwcap(u)=0
00915:  *hwcap(l)=803135
00915:  platform(u)=80000
00915:  platform(l)=0
00915:  _DL_HWCAP_PLATFORM(u)=f0000
00915:  _DL_HWCAP_PLATFORM(l)=0
00915:    trying file=/usr/lib/libcrypto.so.0.9.7

This is the only 'sid' box I've got so I can't test the other cases.

Cheers,
